I noticed that zpool scrub on a certain pool runs "like forever".
I decided to monitor its progress using periodic zpool status command,
once in 10 seconds.
Here's a snippet from the capture around an interesting point.
Please notice two highlighted reports ('oops').
This is stable/7.
Thank you in advance for insights/comments.
